| Gen 1 Image Intensifier Tube | Basic surveillance, hunting, low-budget | FOM ~900 (minimal light amplification), 45-65 lp/mm resolution (ISO 12233), GaP photocathode | Lower cost, lightweight, no maintenance required | High noise, short lifespan (500-1,000 hrs), poor low-light performance |
| Gen 2 Image Intensifier Tube | Military, law enforcement, professional | FOM 1,200–1,800 (ISO 12232), 65–72 lp/mm resolution, GaAs photocathode (ASTM F1313) | Improved sensitivity, durable, autogating ▲ (some models) | Higher cost than Gen1, requires periodic alignment, moderate lifespan (2,000 hrs) |
| Gen 2+ (Our Product) | Advanced surveillance, tactical ops | FOM 2,000+ (▲ vs Gen2), 72–78 lp/mm resolution, Autogating (ANSI/ASQC Z5.1), 18mm photocathode | Enhanced light sensitivity, 43mm P45 compatibility (fits ANVIS goggles), 3,000+ hrs lifespan | Premium pricing, requires controlled storage (moisture-sensitive) |
| Gen 3 Image Intensifier Tube | High-end military, extreme conditions | FOM 2,600+ (▲ vs Gen2+), 64–72 lp/mm resolution, Ion-barrier coating (MIL-STD-810H) | Best-in-class sensitivity, longest lifespan (5,000+ hrs), UV/IR compatibility | Extremely expensive, strict handling requirements, no autogating in base models |
| Thermal Imaging Camera | No-light environments, SAR missions | Thermal detection (ASTM E1965), 30–60 Hz refresh rate, 17–30 µm resolution (IEEE 1223) | Works in total darkness, immune to light pollution, detects heat signatures | Bulky design, lower resolution for detail, affected by thermal interference |
| Digital Night Vision System | Consumer use, day/night monitoring | CCD sensor (ISO 12233), 1x magnification (system-dependent), digital enhancement (JPEG 2000) | Affordable, day/night operation, compact size | Poor low-light performance, requires ambient light, image lag (▲ vs analog) |
